The first synthesis of an isosteric phosphonate analogue of the aminotriol lipid phytosphingosine (3), together with an improved synthesis of (2S,3S,4S)-phytosphingosine (2), are described. A key intermediate is 3-pentylidene acetal 9, which was prepared in two steps from dimethyl 2,3-O-benzylidene-d-tartrate (7).
描述了氨基三醇脂质植物鞘氨醇(3)的等构膦酸酯类似物的首次合成,以及(2S,3S,4S)-植物鞘氨醇(2)的改进的合成。一个关键中间体是3-亚戊基乙缩醛9,这是在两个步骤中制备选自二甲2,3- ø -benzylidene- d -酒石酸盐(7)。
